Kris Commons travelled down to London to have an injection in his spine in a bid to ensure that he would be ready for the start of Celtic's pre-season, The Scottish Sun reports.

The forward had reportedly been troubled by a problem towards the bottom of the back for several weeks, according to The Scottish Sun, so underwent the injection to relieve some of the swelling.

And The Scottish Sun reports that the 32-year-old will be back training as early as next Monday in an attempt to prove his fitness for the start of the next campaign.

The news will ultimately prove to be a boost for Ronny Deila's replacement at Parkhead as the swift return to training should ensure that Commons will be ready for the start of the Hoops' Champions League campaign. Celtic's first involvement will come in the second qualifying stage which begins in mid-July, which leaves the new boss with little time to make significant changes before the tie.

And after struggling for opportunities under Deila this past season, Commons will surely be looking at the coming months as an excellent chance to put himself in the Norwegian's successor's plans.

After making just 19 appearances in the Scottish Premiership this past campaign, he will be hoping to prove that he still has the quality to score bags of goals like he did during the 2013-14 season when he managed 27 strikes in the league.
